Release Notes

scssphp/scssphp (scssphp/scssphp)

v2.0.0: 2.0.0

Compare Source

This release is a full rewrite of the compiler. The new implementation is a port of dart-sass,
making it spec-compliant and easier to update to support new Sass features. However this release
does not implement Sass modules yet.

BC breaks

• The Compiler class is now final
• The LoggerInterface now expects more argument in its method signatures
• \ScssPhp\ScssPhp\OutputStyle is now an enum instead of a class with string constants.
• Compiler::setOutputStyle now expects an instance of the OutputStyle enum instead of a string.
• Deprecated methods of the compiler have been removed.

Deprecated

• Deprecate passing a path as string as the Compiler::compileString second argument. Either pass
  a URL or use Compiler::compileFile instead. (@​stof)

Removed

• Remove support for color math in Sass expressions (@​stof)
• Remove the CLI shipped in the package (@​stof)
• Remove the scss.inc.php file. Use the autoloader generated by Composer instead. (@​stof)
• Remove the cache system integrated in the compiler (@​stof)
• Remove support for PHP < 8.1 (@​stof)

Added

• Add support for PHP 8.4 (@​stof)
• Add support for the Sass indented syntax (@​stof)
• Add a representation of Sass values using PHP value objects (@​stof)
• Add the Importer extension point for custom importers (@​stof)
• Add support for configuring the reporting of deprecation with Compiler::setSilencedDeprecations,
  Compiler::setFutureDeprecations and Compiler::setActiveDeprecations (@​stof)
• Add support for silencing deprecations from dependencies with Compiler::setQuietDeps (@​stof)
• Add support for configuring verbosity of deprecation warnings with Compiler::setVerbose (@​stof)

Fixed

• Thanks to the rewrite, scssphp is now spec-compliant, fixing many issues (@​stof)

Changed

• The message received by loggers no longer contains the location and stack trace. Loggers
  need to include them based on the provided argument depending on their formatting needs. (@​stof)
• Custom functions can now be defined using the new representation of Sass values by using
  \ScssPhp\ScssPhp\Value\Value as return type. Untyped functions will still receive legacy
  values. (@​stof)
